SIX-WHEEL CAR-TRUCK CONSTRUCTION.

Application filed February 10, 1927.

This invention relates to improvements in six wheel car true templatesequalizing equalizing ends with member inner further contemplat andtransverse b0 side-frames, end members k constructions and coneachcoii'iprising and a central flexibly connected at its end portions ofthe end members, wear means being such flexible connections andinterposed at the invention es three part side frameslsters, springseats supportedin bolster openings of the end side frame members intowhich oaenin s the bolsters extend and between which seats and thetransverse bol posed, said spring seats b brackets to suppo stcrs,springs are interng provided with rt inner brake hangers,

outer brake hanger brackets being interlocked with theouter bers oftheside fr ends of the end memames and secured by the same bolts whichsecure axle boxes to said end members.

In the accompanying dr i Figure 1 is a side elevation of a six wheeltruck embodying the improvements;

versely through the flanges 5 and freely through a transverse hole 7 inthe end mem her 1 (or and one of said flanges is provided with a lug Stobe engaged b the angular head 9 on said bolt, the other end of thelatter being threaded to receive a nut 10, between which and a boss 11on one of said flanges, a washer 12 is interposed. Thefree end of eachend member 1--2 is provided with a socket 18 receiving a shank 14: on awear block or plate 15 disposed at the inner end of each member l2. Thehorizontal weblti at each end of the central member is provided with ahole 17 which receives a shank 18 depending from a bottom wear plate orblock 19 seated on said web 16 and engaged by the upper wear block orplate 15. Instead of providing a separate bottom 'wear plate or block,the web of the central member 3 at each end thereof may l)6 l1'18.l6thicker and constitute a wear pad to be engaged by the wear plate orblock 15, such construction being indicated at 20, Figure 6.

Journalboxes are secured of bolts 3l and plates 32 to the end members ofthe side frame as shown in Figure l and the central equalizing member isprovided with an integral axle box construction 33. Each of the endmembets 1 and 2 of the side frame is provided with a bolster opening 34which receives the end portion of a bolster 35, the latter being loatedat respective sides and spaced from the central axle 36, the latterbeing mounted in the axle boxes of the central or equalizing member 3while the ai le 37-37 at the ends of the truck being mounted in the axleboxes secured to the end members 1-2 of the rctpective side frames.Spring seats 38- -38 are located in the openings in the members 1 and E2and interlockingly engaged with the latter as at 38. Between these seatsand the trai'isverse holsters 35, springs "9 are disposed. Each of thespring seats 38 is provided with an inwardly projecting bracket 410adapted for the reception and simpoi't of a brake hanger, "said bracketsbeing located intermediate of the wheels 41-42 43. Lo cated upon andhaving interlocking connection with the ends of the members 1 and 2which project over the axle boxes carried by said members, are forwardlyprojecting brackets 14, the latter being secured in place framecon'iprises bar 456, the latter for the side frames side frame by abridge constituting guide means and the transverse bolsters and thelatter having guides 47-t8 for the bridge bar to maintain properalignment of the latter.

A longitudinal holster 4-9 is disposed intermediate the transversebolsters and is pro- 'vided at its respective ends with reduced portions50 which enter the transverse bolsters and said longitudinal bolster isformed with shoulders 51 to engage the transverse bolsters and maintainthem in proper positions. The upper and lowerportionsot each transversebolster are provided with aligning openings ea-53 and the longitudinalbolster is provided with an opening 54 which aligns with the openings52-53 and through said openings a vertical pin or key 55 is passed andsecured. against displacement by means of a cotter 56.. By thus keyingthe longitudinal bolster the. ends thereof to the transverse bolsters,spaced relation between the transverse bolsters will be insured.

We do not, in this application, claim the pin or key connection betweenthe longitudinal and transverse bolsters, such construc tion beingcontemplated by application filed in the name of G. T. Johnson, filedFebruary 10th. 1927-, and designated by SerialNo. 167.279.

Havingfully described our invention what we claim new and desire tosecure. by LcttersPatent, iszr 1. A six wheel truck in which each sidetwo end members flexibly connected respectively with ends ota centralequalizing; member, and wear means inteiv posed in the flexibleconnections between said end and flexible members, p

2. A six wheel truck in which each side frame comprises two end membersflexibly connected respectively with ends of'a central equalizingmember. and wear means interposed in the flexible connections betweensaid end and flexible members, said wear means including wear membersconnected with the inner end portions ofthe end mem bers of each sideframe.

3. A six wheel truck in which each side frame comprises two end membersflexibly connected respectively with ends of a central equalizingmember, and wear "means interposed in the flexible connections betweensaid end and flexible members, said wear means interposedbetween eachendv member and ,ends of the transverse bolsters are connected ad acenteach the central member, including two .contacting wear members.

1. A six wheel truck in which each side frame comprises two endmembersflexibly connected respectively with ends of a central equalizingmember, and wear means interposed in the flexible connections betweensaid end'and flexible members, said wear means comprising pairs of wearplates, the plates of each pair being removably connected-With end andcentral members respectively ot the side frames. 7 i
